I Have A Feeling It's A No On This One. Lol.  

No can't say I have but I was thinking to be Uber safe some latex briefs with a built in condom! LOL  
Or a latex face mask HaHa! I just love daty lick lick

....a number of years ago, a gal who advertised that "everything was covered" put down a piece of Saran wrap over the promised land for my tongue to cope with. Needless to say the session went nowhere fast. Cautious yes, paranoid no. BTW, I think she's still around with a new name and with all of her old reviews expunged. However don't both asking who she might be; that's one place I won't go.  Ciao!
